Explore the concept of vulnerabilities, which are security flaws in a system. Lisa Bock introduces the Open Web Application Security Project (OWASP) Top 10 List, and Common Vulnerabilities and Exposures. Discover ways to safeguard your system include performing ‘white list’ input validation, and using Content Security Policy.
- [Voiceover] When developing security strategies…it's important to understand the following terms,…Assets, Risks, Threats, and Vulnerabilities.…Assets are tangible and intangible items…that can be assigned a value.…Risk is exposure to an event by a person or other entity…that might result in business disruption,…financial loss, or even loss of life.…Risk is a function of a threat exploiting a vulnerability…according to a formula,…Risk = Threats times Vulnerabilities.…
In order to understand the risk to assets,…possible threats and vulnerabilities must be evaluated.…A threat is something that might happen…and can range from innocent mistakes by employees…to natural disasters.…And in general, they're difficult to control.…Threats include disgruntled employees,…terrorists, or nature.…A threat is anything that can exploit a vulnerability,…intentionally or accidentally,…and obtain, damage, or destroy an asset.…
A vulnerability is a security flaw in a system…that can be exploited by threats.…The goal is to gain unauthorized access to an asset.…
Security expert Lisa Bock starts with an overview of ethical hacking and the role of the ethical hacker. She reviews the kinds of threats networks face, and introduces the five phases of ethical hacking, from reconnaissance to covering your tracks. She also covers penetration-testing techniques and tools. The materials map directly to the "Introduction to Ethical Hacking" competency from the CEH Body of Knowledge, and provide an excellent jumping off point for the next courses in this series.
Note: Our Ethical Hacking series will map to the 18 parts of the EC-Council's certification exam. Find more courses in the series on Lisa's author page.
